Further, the tray 55 is provided with positioning convex portions 57 a to 57 e that are recessed upward to be fitted to the convex portions 18 a to 18 e of the upper surface portion 15. Further, as shown in FIG. 6, the tray 55 of the present embodiment can be taken out and inserted substantially horizontally from the opening of the accommodation space 23 opened by the lid body 22 with the cage 50 disposed in the accommodation space 23. It has a simple structure. Specifically, the tray 55 has a width smaller than that between the leg portions 54 a and 54 b of the cage 50, and is detachable from the lower portion of the cage 50. The tray 55 is provided with protrusions 58a and 58b that protrude laterally on the rear side in the insertion direction. These protrusions 58a, 58b are formed such that the width between the front ends in the lateral direction is larger than the width between the legs 54a, 54b of the cage 50, and are disposed on the tray positioning portions 21a, 21b of the upper surface portion 15 in the normal arrangement state. By this, it is located in the front side of the leg parts 54a and 54b of the cage 50.

  When the user who uses this tableware dryer cleans the tray 55, the tray 55 can be taken out and cleaned in a state where the basket 50 is taken out from the storage space 23. Further, as shown in FIG. 6, the basket 50 can be taken out and washed while being placed in the housing space 23 of the dryer body 10. Therefore, since the user can select a usage method according to his / her wishes, convenience can be improved.

  The cleaned tray 55 can be arranged in a state where the basket 50 is taken out from the accommodation space 23. At this time, in the present embodiment, the tray body 10 is provided with the tray positioning portions 21a and 21b and the tray 55 is provided with the protrusions 58a and 58b. Can not. Further, even if the user does not notice the abnormal arrangement of the tray 55, the legs 54c and 54d of the basket 50 are placed on the protrusions 58a and 58b of the tray 55 when the basket 50 is arranged later, and the basket 50 is properly arranged. Cannot be placed in position. Furthermore, even if the user does not notice the abnormal arrangement of the tray 55 and the basket 50, in such an abnormal arrangement state, the lid 50 cannot be closed due to interference because the cage 50 is positioned above. Therefore, it is possible to prevent the drying operation from being performed in the abnormal arrangement state.

  Further, when the cleaned tray 55 is arranged in the accommodation space 23, the basket 50 can be inserted into the lower portion of the basket 50 while being arranged in the accommodation space 23 of the dryer body 10. At this time, even if the tray 55 is to be inserted from the side of the protrusions 58a, 58b, the width between the protrusions 58a, 58b cannot be inserted because the width between the legs 54a, 54b of the basket 50 is larger. Further, when the tray 55 is inserted while holding the protrusions 58a and 58b, the front side in the insertion direction in which the positioning protrusions 57a, 57d, and 57e are provided can be inserted between the legs 54a and 54b of the cage 50. Further, when the protruding portions 58a and 58b of the tray 55 abut against the leg portions 54a and 54b of the basket 50, no further insertion is possible. In this state, the protrusions 58a and 58b of the tray 55 can be arranged at the normal arrangement positions arranged on the tray positioning parts 21a and 21b by being arranged on the upper surface part 15. Therefore, when the tray 55 is disposed in a state where the basket 50 is disposed in the accommodation space 23, the abnormal arrangement of the tray 55 can be prevented.

  On the other hand, there is a possibility that the user misuses that the drying operation is performed by putting the hook 100 on the upper frame portion 52 of the basket 50. In this case, when the drying operation is started, the warm air supplied from the blower outlet 45 to the accommodation space 23 is supplied to the lower region of the accommodation space 23 in which the tray 55 is disposed.

  Specifically, when the basket 50 with the hook 100 is placed after the tray 55 is placed in the accommodation space 23, as shown in FIGS. It is placed on the tray 55 and deformed by the central positioning convex portion 57a. As a result, a ventilation channel (gap) is formed between the hook 100 and the tray 55 on both sides of the positioning convex portion 57a. Therefore, when warm air is supplied from the blower outlet 45 to the accommodation space 23 in this state, the air is ventilated to the lower part of the accommodation space 23 on the tray 55 from the gap between the hook 100 deformed by the positioning convex portion 57a and the tray 55. The Moreover, the lower part of the accommodation space 23 is ventilated while the lower part of the hook 100 is bent by the warm wind from the blower outlet 45. This is because the upper part of the blower outlet 45 is in a state where the moisture-containing hook 100 is in close contact with the protective wall part 47, and therefore the upward gas flow resistance is large. Further, this close contact action is due to the upper frame portion 52 of the cage 50 being located further on the back side beyond the air outlet 45 (protective wall portion 47).

  Further, when the basket 50 with the hook 100 is placed before the tray 55 is placed, as shown in FIG. 8, the lower end portion of the hook 100 is placed on the upper surface portion 15 of the dryer main body 10, The projection 18a is deformed. Thus, ventilation channels (gap) are formed between the hook 100 and the upper surface portion 15 on both sides of the convex portion 18a. When the tray 55 is arranged in this state, the lower part of the hook 100 is located at the lower part of the tray 55 as shown in FIGS. As a result, the gas flow resistance in the lower part of the hook 100 is also increased. However, in this embodiment, the air flow path for warm air is formed on both sides by the convex portions 18a provided in the dryer main body 10. Therefore, the warm air can be sent through the ventilation passage between the tray 55 having a high heat resistance temperature and the upper surface portion 15 of the dryer main body 10, and the temperature can be lowered between the tray 55 and the outside in the housing space 23.

  Thus, the tableware dryer of this invention will be in the state which closed the blower outlet 45 completely, even when it hooks the hook 100 on the basket 50 by the convex part 18a provided in the dryer main body 10, and is misused. Can be prevented. As a result, it is possible to prevent the resin molded parts around the air passage 38 and the air outlet 45 from being overheated and melted by the hot air supplied from the air outlet 45.

  Moreover, since the tableware dryer of this embodiment makes the tray 55 detachable in the state which has arrange | positioned the basket 50 to the dryer main body 10, if misuse with the hook 100 is performed, it will be easy to generate | occur | produce melting. It is a configuration. However, the convex portion 18a is provided so as to extend toward the rear wall portion (lower portion 13a) on the lower side of the air outlet 45, and a protective wall portion 47 protruding forward from the air outlet 45 is provided on the upper portion of the air outlet 45. Yes. Therefore, the ventilation channel from the blower outlet 45 can be ensured reliably.

Moreover, when the positioning projection 57a is placed on the tray 55 with the hook 100 hung on the basket 50, the positioning projection 57a functions to secure the ventilation channel by deforming the hook 100 similarly to the projection 18a. Even during such misuse, it is possible to prevent melting of resin molded parts around the air outlet 45. Further, when the tray 55 is taken out by the protective wall 47 provided at the upper part of the air outlet 45, when water is collected on the tray 55, the water prevents the air outlet 45 from entering the inside. it can.

  FIGS. 10A and 10B show a tableware dryer according to the second embodiment. In the second embodiment, when the hook 50 is hung on the basket 50, the supply of hot air to the lid 22 (upper) having a low heat-resistant temperature is surely prevented and can be regulated to flow downward. This is different from the first embodiment.

  Specifically, the basket 50 of the second embodiment is provided with a contact frame portion 59 that protrudes toward the protective wall portion 47 at a portion disposed on the back side. The contact frame portion 59 includes a pair of bent frame portions 59a that protrude from the lower frame portion 51 to the back surface, and a linear frame portion 59b that joins the top portions continuously. The contact frame portion 59 forms a bent frame portion 59 a so that the filament frame portion 59 b substantially contacts the protective wall portion 47.

  In this tableware dryer, when the basket 50 is placed in the accommodation space 23 with the hook 100 being hung on the upper frame portion 52 of the basket 50, the hook 100 is sandwiched between the linear frame portion 59b and the protective wall portion 47. It is. And the lower part of the hook 100 hangs down like 1st Embodiment, and makes the state pinched | interposed on the tray 55 or between the tray 55 and the upper surface part 15 like illustration. When the user performs a drying operation in this state, the warm air supplied from the blower outlet 45 is blocked from flowing upward and can only flow downward. Therefore, the air is ventilated from the top of the tray 55 having a high heat resistance temperature or between the tray 55 and the upper surface portion 15 to the front side. As a result, it is possible to prevent hot air from being intensively supplied to the upper lid body 22 having a low heat-resistant temperature, and the lid body 22 from being melted.

  In addition, the warm air supply apparatus of this invention is not limited to the structure of the said embodiment, A various change is possible.

  For example, in the above-described embodiment, the tray 55 is configured to be detachable in a state where the basket 50 is disposed with respect to the dryer main body 10, but the tray 55 is provided with a plan view shape larger than the lower frame portion 51 of the basket 50, The structure which arrange | positions the basket 50 on the tray 55 may be sufficient. In this case, the convex part for deforming the hook 100 is constituted by the positioning convex part 57 a of the tray 55. Further, the convex portion is not limited to the upper surface portion (bottom wall portion) 15 and the tray 55 of the dryer main body 10, and is directed from the lower portion (rear wall portion) 13 a of the blower outlet arrangement portion 13 and the protective wall portion 47 toward the cage 50. And may be configured to protrude from the basket 50 toward the air outlet 45.

  And in the said embodiment, although the tableware dryer which dries tableware was applied and demonstrated as the warm air supply apparatus of this invention, the sterilization which accommodates a predetermined instrument in the accommodation space 23 and sterilizes with warm air Even if it is a machine, the same operation and effect can be obtained.
